feat(install): Add one-shot installation script

- Create comprehensive one-shot installer with robust error handling
- Includes network checks, disk space validation, and retry logic
- Handles existing installations gracefully (idempotent)
- Updates README with quick install command prominently featured
- Manual installation instructions moved to collapsible section

The script provides explicit error messages and never fails silently.
All prerequisites are validated before starting installation.
